The Sheridan PGP is a stock class marker that holds 10 paintball rounds in the top tube of the gun. This tube is not spring loaded and you must rock the gun back when pumping to load the next paintball in the chamber. This was one of the first paintball pump guns that I played with. I'll never forget the time I was playing in a field, I was sitting down at the grass level and my brother came running out from nowhere and sat down in front of me facing the opposite direction.. I was so excited! I pulled the trigger and the gun fired but there was no paintball loaded into the chamber, so I quickly reloaded and fired again, Still no paintball was shot. At this point he turned around with his VM68 3 feet away from me and asked me if I wanted to run away.. So naturally I did..

The Sheridan P68 is essentially a PGP with a longer barrel and a larger feed tube.

This marker was a great gun! The person that I bought it from had a brass barrel on it. It made a wonderful *ping* sound every time it was fired.

The Auto Cocker has been around for a Long time, it's a tried and true high end mechanical marker. The semi auto Cocker is very popular and can be seen with many different upgrades.
